This morning's Nintendo Direct confirmed two new Zelda games for Wii U, namely a HD remake of GameCube game Wind Waker with improvements to gameplay and graphics, and a brand new entry that will address series conventions like "completing the dungeons in a certain order", and to "play by yourself." The Wind Waker HD remake is confirmed for release "by this fall."
Also they mention a new Zelda game will come at some time later but who couldn't guess that.
